Takotsubo syndrome (TTS) has been known to have a favorable prognosis. Beta-blockers are reported to be effective for TTS patients with cardiogenic heart failure due to left ventricular outflow tract (LVOT) obstruction. However, there is no report on ultrashort-acting beta-blockers being used for treating TTS, and there are no clear guidelines for their dosages or applications. Herein, we describe a 72-year-old woman in whom landiolol hydrochloride was used in the acute phase of TTS with LVOT obstruction. In this case, the dose of landiolol hydrochloride was increased to 10 μg/kg/min, resulting in improvement of LVOT obstruction, which led to hemodynamic stabilization.
已知应激性心肌病（TTS）预后良好。据报道，β受体阻滞剂对因左心室流出道（LVOT）梗阻导致的心源性心力衰竭的TTS患者有效。然而，尚无关于使用超短效β受体阻滞剂治疗TTS的报道，其剂量或应用也没有明确的指南。在此，我们描述一名72岁女性，在TTS合并LVOT梗阻的急性期使用了盐酸兰地洛尔。在该病例中，盐酸兰地洛尔的剂量增加至10μg/kg/min，导致LVOT梗阻改善，从而实现血流动力学稳定。
